OK everyone, here is an update:
The server crashed again overnight. This time, the following error
messages were on the console:

I have been able to move all workloads onto other servers. As at least
two people suggested, I booted from the HP SmartStart CD and ran 100
loops of systems diagnostics and tests, especially for the memory and
CPU. No problems were found. I think I will run memtest86 over the
weekend.
We have placed a hardware support call in to HP.
